Question

sắp xếp các phân số 3/4; 2/4; 1; 6/5 theo thứ tự tăng dần

 

Answer 1

\(\dfrac{3}{4}=\dfrac{3\times5}{4\times5}=\dfrac{15}{20}\)

\(\dfrac{2}{4}=\dfrac{2\times5}{4\times5}=\dfrac{10}{20}\)

\(1=\dfrac{20}{20}\)

\(\dfrac{6}{5}=\dfrac{6\times4}{5\times4}=\dfrac{24}{20}\)

Vì \(\dfrac{10}{20}< \dfrac{15}{20}< \dfrac{20}{20}< \dfrac{24}{20}\) nên \(\dfrac{2}{4}< \dfrac{3}{4}< 1< \dfrac{6}{5}\)
